Daily Weekly Monthly Yearly Opens

This script plots the current daily, weekly and monthly opens (all enabled by default).

Here are some additional info about the drawing behavior:

• Daily open is shown only on intraday timeframes
  
• Weekly open is shown only on timeframes < weekly
  
• Monthly open is shown only on timeframes < monthly
  

Notes de version:

Add an option to show tails on opens (disabled by default). Tails can help to better visualize how price previously traded at these levels.

In addition, for low timeframes, it provides a work around for PineScript not drawing a line if the open isn't yet visible on the screen.

Notes de version:
